Description
STAMBP Human Recombinant produced in E.coli is a single,
non-glycosylated polypeptide chain containing 447 amino acids (1-424) and
having a molecular mass of 50kDa. STAMBP is fused to a 23 amino acid His-tag at N-terminus
& purified by proprietary chromatographic techniques.
Synonyms
STAM-binding protein, Associated molecule with the SH3
domain of STAM, Endosome-associated ubiquitin isopeptidase, AMSH, EC 3.1.2.15,
EC 3.4.19, MICCAP.
Introduction
STAM Binding Protein (STAMBP) is a zinc metalloprotease which specifically cleaves Lys-63-linked polyubiquitin chains, however it doesn’t cleave Lys-48-linked polyubiquitin chains. STAMBP has a role in signal transduction for cell growth and MYC induction mediated by IL-2 and GM-CSF. In addition, STAMBP potentiates BMP signaling by antagonizing the inhibitory action of SMAD6 and SMAD7. STAMBP also has a major role in regulation of cell surface receptor-mediated endocytosis and ubiquitin-dependent sorting of receptors to lysosomes. Endosomal localization of STAMBP is essential for efficient EGFR degradation but not for its internalization. STAMBP is also involved in the negative regulation of PI3K-AKT-mTOR and RAS-MAP signaling pathways.
Physical Appearance
Sterile Filtered colorless solution.
Formulation
STAMBP protein solution (1mg/ml) containing 20mM Tris-HCl
buffer (pH 8.0), 0.15M NaCl, 10% glycerol and 1mM DTT.
Stability
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid multiple freeze-thaw cycles.
Purity
Greater
than 85% as determined by SDS-PAGE..
